The coronavirus is serious business, but the internet is having fun with an official federal graphic about facial hair and optimum mask efficiency.

The document comes from a 2017 blog post on the website of the Centers for Disease Control and Prevention. Keyed to the start of “No-Shave November,” the graphic depicts 36 facial hairstyles and indicates which might interfere with the “tight facepiece seal” needed when using a respirator.

The entertainment value of the graphic is enhanced by the names assigned to some of the mustache/beard options, such as the Hulihee, the French Fork and the Balbo.

Jobs with state and city governments are usually a source of stability in the U.S. economy, but the financial devastation wrought by the coronavirus pandemic has forced cuts that will reduce public services — from schools to trash pickup.
